The family of the London teenager whose body was found in a Malaysian jungle on Tuesday have urged the police to continue to investigate the case as a possible crime after foul play was ruled out by an autopsy. The Malaysian police said on Thursday that a post mortem had shown that Nora Quoirin, 15, had likely starved and died of internal bleeding after being lost for about a week in the jungle near the Dusun eco-resort. Nora, who had serious learning disabilities, disappeared from her family's holiday bungalow on August 4 and is believed to have died two to three days before her body was found.However, Charles Morel, the French lawyer of her Franco-Irish parents, who believe she may have been abducted, told The Daily Telegraph that her family still 'aren't ruling anything out' as they 'remain convinced that it is improbable that Nora left the bungalow voluntarily.' The authorities must explore the possibility of a 'criminal act,' he added. 'We want to make sure not only that this [criminal] hypothesis is not ruled out, but that [the investigators] work on it' taking into account the importance of tourism in Malaysia and its image, the authorities may tend to prioritise the thesis that she left [voluntarily] over the criminal hypothesis,' said Mr Morel.

Nora was born with holoprosencephaly, a neurological disorder, which limited her speech and coordination, her parents revealed in an earlier statement. The location where she was found means she would have had to follow 'an extremely steep path through the jungle,' said Mr Morel. On Thursday, state police chief Mohamad Mat Yusop, said that the autopsy, which was conducted on Wednesday in the presence of foreign officials, had concluded that the teen suffered 'bleeding in her intestines due to not eating' as well as 'extreme stress'.

The Malaysian police have classified her disappearance as a missing persons case. However, earlier this week, the Paris prosecutor's office said it had opened a criminal investigation into Nora's death, which is normal practice for French prosecutors who regularly investigate cases involving French citizens abroad. Nora's family have not commented publicly since the autopsy results. In a statement released Wednesday by The Lucie Blackman Trust, a charity that supports relatives of British people missing overseas, her relatives said she was the 'heart' of the family. 'She is the truest, most precious girl and we love her infinitely. The cruelty of her being taken away is unbearable. Our hearts are broken.'
